Introduction
Their outstanding performance of the LD Systems DDQ series is the result of a precise design and perfect
features that deserve top marks across the board.
The DDQ systems are loaded with Faital Pro woofers and BMS tweeters. They are driven separately by two Hypex
UCD400 400W power stage modules.
The signal is processed by a Sharc DSP programmed especially for the DDQ active systems with converters that
have a remarkable dynamic range of 127dB. It handles all protection functions, whereby the predictive peak
limiter is especially worthy of mention. With a look ahead time of 1 millisecond, it ensures absolutely distortion-
free reproduction even at maximum volume.
The bass-reflex cabinet of the DDQ active speaker is made of multiplex. Thanks to the innovative Evolutive
handles and their comparatively low weight, the DDQ 10" and 12" active speakers are easy to transport. They
are designed for all PA applications: for mobile use, permanent installation, compact systems, FOH systems or
delay lines. Thanks to their integral 50° angle, they can also be used as active monitors. All DDQ systems are
made in Germany!

13. Make certain that objects cannot fall into the device.
14. Use the device only with accessories with which the manufacturer intends the device to be used.
15. CAUTION: If this device has a mains connector equipped with protective earth, it must be connected to a
mains socket with a protective ground connection. Never disable the function of the protective ground connection
of the included power cord.
16. Do not turn on the device immediately if it was exposed to strong temperature fluctuations (for example after
transportation). Moisture and condensation may damage the device. Leave the device switched off until it has
reached room temperature.
17. Do not open the device and do not make any changes to the device.
18. Before connecting to mains power, make certain that the mains voltage and the mains frequency are the
same as the operating values of the device (see type label). If the device is equipped with a supply voltage selec-
tor switch, make certain that the values of the device match the values of the mains power before connecting.
If the plug on the included cord does not fit your mains outlet, contact your electrician.
19. Make certain that the power cord is not stepped on. Protect the power cord against pinching, especially at
the device plug and the power plug.

concern, since the internal audio limiter compen-
sates for over-modulation. Permanent illumination
should be avoided by reducing the input level.

FRONT OF HOUSE CONFIGURATION
For the front of house application, the narrower side of the HF horn opening must face downward.
STAGE MONITOR CONFIGURATION
For use as a stage monitor, the LDDDQ10 and LDDDQ12 can be position lying on their sides (horizontal setup). If
necessary, the HF horn can be rotated by 90° in order to attain a greater
HF dispersion angle. To do this, the active speaker must first be switched off and disconnected from the mains.
Next remove the front grille and loosen and remove the screws on the mounting flange of the horn . Afterwards
the horn can be rotated by 90° and re-fastened (please never rotate more than 90°). If the HF horn is to rotated
back for a vertical setup, this must always be done in the opposite direction. Rotating the HF horn multiple times
in the same direction can damage the leads to the HF system or its terminals.

INSTALLATION & MOUNTING:
ADJUSTING THE SM707 CABINET FLANGE
The built-in, patented SM707 cabinet flange is highly adjustable.
The SM707 permits angles of between + und - 13.5° in increments of 4.5°.
Carefully lift the cabinet a little (approx. 0.5 cm) to unlock the locking mechanism, then tilt the cabinet to the
desired position and lower it again.
FLOWN OPERATION:
The speakers are equipped with appropriate flyware for flown operation.
The LD DDQ series speakers have M8 threads for use with M8 eyelet bolts, which can be used to suspend the
speakers
on chains with snap hooks or wire ropes.
Please use only appropriately certified, undamaged flyware (flying points,
eyelet bolts, snap hooks, chains, wire ropes, etc.). Please also observe the corresponding requirements
for flown operation above persons in correspondingly applicable regulations (varies from country to country)!
As an alternative to flying points, the speakers can be flown using the LDDDQ10SB and LDDDQ12SB swing bra-
ckets developed especially for the LD DDQ series. The assembly instructions can be found on the next two pages
of this user's manual. The swing brackets can be fastened securely to crossbar systems, for example, using the
optional Adam Hall SCP838 "self-lock" hooks.
MAINTENANCE:
The best way to clean the surface of the loudspeaker‘s cabinet is to use a dry, medium-hard brush (wallpaper
brush). Use only a dry cloth to clean the control panel.
